- Atoms that do not lose electrons easily
but attract electrons usually form covelent bonds.
- The positive nucleus of both atoms has
an equal attraction for the electrons being shared.
- The shared electrons spend most of their
time between the two atoms.
- It is the attraction between the nucleus
and the shared electrons that holds the atoms together.
- Diatomic molecules. When found in
nature a pure elements, these seven elements exist only as two atoms
- Hydrogen - H2
- Nitrogen - N2
- Oxygen - O2
- Florine - F2
- Chlorine - Cl2
- Bromine - Br2
- Iodine - I2
- Polyatomic ion - a
group of covalently bonded atoms that acts like a single atom when
combining with other atoms. Overall, this group of atoms is not
electrically balanced and does have a total charge.
